Appeal 2007-3837
Application 10/631,897
1 5. Christopher describes that the weighting circuits 504, 506 and 508
2 “may be simple hard-wired bit shift arrangements.” (Christopher, col. 9, ll.
3 12-14).
4 Applicant’s arguments
5 6. Applicant argues that claim 5 requires that each of the plurality of
6 signal lines is individually shifted a number of bits, and that Christopher’s
7 weighting circuits 504, 506, and 508 do not act on the input signal 500 but
8 on signal 503 (Br. 9).
9 7. Applicant also argues that there is no switch in Christopher with
10 the function recited in claim 5 for selecting outputs of said plurality of signal
11 lines or all “0” (Br. 10).
12 Examiner’s response
13 8. The Examiner responded and further found that Christopher
14 describes that the output of the weighting circuits 504, 506 and 508, which
15 are hardwired bit shift arrangements, operate on the input signal as claimed
16 (Answer 4).
17 9. The Examiner further found that gating elements 510, 512, and 514
18 (FIG. 6) meet the switching means limitation since the outputs of the gating
19 elements provide either signals in the parallel lines (when enabled) or
20 otherwise zero (when disabled) to the adder 502 in response to control
21 signals (Answer 5).
